The probability of drawing one black seven from a standard deck of cards is 2/52 = 1/26. The probability of drawing the other black seven from the remaining 51 cards is 1/51. Therefore the probability of drawing both black sevens from a deck of cards = 1/26 x 1/51 = 1/1326 ~ 0.000754 (3sf).
If you are drawing only two cards, the probability that they will both be aces is one in 221. ( (52 / 4) * (51 / 3) ) If you are drawing all the cards in the deck, one at a time, the probability that you will draw at least two aces in a row is much better than that, but how much better I leave for someone else to answer.
The probability of drawing a king on the first draw is 4/52 = 1/13. The probability that the next card is one of the 3 remaining kings is 3/51 = 1/17. The probability of both events is (1/13)*(1/17) = 1/221
The probability of drawing two Aces from a standard deck of 52 cards is 4 in 52 times 3 in 51, or 12 in 2652, or 1 in 221, or about 0.00452.
The probability of drawing the Ace of Hearts from a standard deck of 52 cards is 1 in 52. The probability of then drawing the Ace of Diamonds is then 1 in 51. Multiply these two probabilities together, and you get 1 in 2652, or about 0.0003771.The probability of drawing the ace of hearts from a deck before drawing the ace of diamonds, ignoring any other cards, is 1/2.Note: Both of these answers are correct. It depends on your point of view. They've been left so that you, dear reader, can think about it.
The probability of drawing two blue cards froma box with 3 blue cards and 3 white cards, with replacement, is 1 in 4, or 0.25.The probability of drawing one blue card is 0.5, so the probability of drawing two is 0.5 squared, or 0.25.
The probability of drawing one black seven from a standard deck of cards is 2/52 = 1/26. The probability of drawing the other black seven from the remaining 51 cards is 1/51. Therefore the probability of drawing both black sevens from a deck of cards = 1/26 x 1/51 = 1/1326 ~ 0.000754 (3sf).
The probability is approx 0.09. This assumes that J and K are not prime numbers.
The probability of drawing a heart from a fair deck is 1 in 4. If the card is replaced then the probability is again 1 in 4. The probability of drawing a card other than a heart is 3 in 4. Once again if the card is replaced then the probability remains 3 in 4
If you are drawing only two cards, the probability that they will both be aces is one in 221.

The probability of drawing two Aces from a standard deck of 52 cards is 4 in 52 times 3 in 51, or 12 in 2652, or 1 in 221, or about 0.00452.
The answer will depend on:whether the cards are drawn at random andwhether or not the first card is replaced before drawing the second.It also depends on how many times the experiment - of drawing two cards - is repeated. If repeated a sufficient number of times the probability will be so close to 1 as to make no difference from a certainty.
The probability of drawing the Ace of Hearts from a standard deck of 52 cards is 1 in 52. The probability of then drawing the Ace of Diamonds is then 1 in 51. Multiply these two probabilities together, and you get 1 in 2652, or about 0.0003771.The probability of drawing the ace of hearts from a deck before drawing the ace of diamonds, ignoring any other cards, is 1/2.Note: Both of these answers are correct.

In a standard 52 card deck, there are 13 clubs and 4 4s. However, the four of clubs is in both lists, so this represents only 16 distinct cards (the 13 clubs, and the 3 other 4s). The probability of drawing one of these 16 cards is 16/52, or 4/13.
There are 52 cards in the deck.The probability of drawing the ace of spades on the first draw is 1/52 .Since you don't put the first card back, there are then 51 cards in the deck.The probability of drawing the 4 of spades on the second draw is 1/51 .The probability of both occuring is (1/52) x (1/51) = 1/2,652 = 0.037707 % (rounded)
In a standard 52 card deck, the probability of drawing an ace is 1/13, and the probability of drawing a diamond is 1/4. The probability of drawing both an ace and a diamond is 1/52.Thus the probability of drawing an ace or a diamond is1/13 + 1/4 - 1/52 = 4/13 or about .308.
